Start with detection of hereditary or acquired spherocytosis, iron‑deficiency anemia, or other causes of microcytosis/hypochromia, and assess RBC hydration status. MCHC is clinically useful for identifying hypochromic states and supporting iron‑deficiency evaluation; values <27 g/dL indicate iron‑deficient red cells per AHA perioperative guideline 1 [Level I evidence].

Indicates average hemoglobin concentration per RBC but is nonspecific; low values can suggest iron deficiency yet normal MCHC does not exclude it (iron deficiency may have normal MCHC in up to 40% of cases) 1 [Level II evidence]. Susceptible to analytic artefacts from dehydrated or undeformable cells causing spurious results 2 [Level III evidence]. Elevated values require ruling out cold agglutinins or lipemia before interpretation 3 [Level III evidence].
